A computationally efficient speech enhancement pipeline in noisy environments based on a single-processor implementation is developed for utilization in bilateral cochlear implant systems. A two-channel joint objective function is defined and a closed form solution is obtained based on the weighted-Euclidean distortion measure. The computational efficiency and no need for synchronization aspects of this pipeline make it a suitable solution for real-time deployment. A speech quality measure is used to show its effectiveness in six different noisy environments as compared to a similar one-channel enhancement pipeline when using two separate processors or when using independent sequential processing.

开发了一种基于单处理器实现在嘈杂环境中计算高效的语音增强管道，用于双侧人工耳蜗系统。定义了一个双通道联合目标函数，并基于加权欧几里德失真度量获得了一个封闭形式的解。该管道的计算效率和不需要同步方面使其成为实时部署的合适解决方案。与使用两个独立处理器或使用独立顺序处理时的类似单通道增强流水线相比，语音质量测量用于显示其在六种不同噪声环境中的有效性。
